Beschreibung
Zusammenfassung:	A variable valve mechanism includes a cam that rotates about a rotating shaft in association with rotation of a crank shaft of an engine, a swinging arm that is disposed between the cam and a valve and is pushed by the rotating cam to swing and push the valve by a first end portion of the swinging arm, and a moving device that moves a second end portion of the swinging arm. Further, there is a regulating member that is coupled to the first end portion of the swinging arm so as to be rotatable and regulates displacement of the first end portion of the swinging arm relative to the valve when the second end portion of the swinging arm is moved by the moving device. The mechanism further includes a connection member that connects the second end portion of the swinging arm to the moving device.
